19 year old skin, is it premature aging? (Photo)

Im 19, have asthma, eczema and allergies. I have recently started a non diary diet due to stomach and skin concerns. My facial texture has however not improved. I have several pimples all over my face and forehead and fine lines, one prominent on my forehead. My large pores and and hyperpigmentation may be due to acne. Although my warts and tear trough runs in the family. Is there anyway I can improve my skin appearance on a budget? Do I look my age or should I be concerned?
